NONSINKABLE BOAT.

Application filed June 9,

This invention relates to boats and is particularly directed to a non-sinkable boat. I Objects of this invention are to provide a boat which is made of metal, which is nonsinkable and sound proof, which is self righting, and which is puncture proof.

Further objects are to provide a boat which may be readily manufactured by ordinary methods without incurring unusual expense, which is of relatively light weight, considering its strength and its carrying capacity, and which is so constructed that the seams are protected against mechanical damage, and

also in which means are provided for protecting the sides against denting, as in contacting with a pier or landing.

An embodiment of the invention is shown in. the aecon'ipanying drawings in which Figure 1 is a plan View of the boat with parts broken away;

Figure 2 is a side elevation partly in sec tion;

Figure 3 is a fragmentary sectional view on the line 3-3 of Figure 2;

Figure 4 is a sectional view on the line 4-4 of Figure 2;

Figure 5 is a fragmentary perspective view showing one of the details of construction.

Referring to the drawings, it will be seen that the boat is provided with a forward air tight compartment 1, and a rear air tight compartment 2. It is formed throughout of inner and outer metal walls 3 and 4 respectively, between which cork or other filling material of this type is positioned, as indicated at 5. It is to be particularly noted from reference to Figure 4 that the sides are separate compartments from that formed by the bottom, and also it will be seen that the end compartments are additional separate and distinct compartments.

The bottom of the boat is provided with a plurality of transverse wood bars 6 which are held in place by means of clips 7 riveted, soldered, or otherwise secured to the bottom sheet or wall, as indicated in Figure 5. This construction followed for the sides of the boat, as is apparent from the broken away portion of Figure 2. Above the transverse bars 6, longitudinally extending slats 8 are positioned, and are relatively closely spaced so as to prevent depression of the top wall of the bottom.

It is to be noted particularly from Figure 4 that each of the joints, as for instance between the top wall 9 of the bottom and the 1926. Serial No. 114,690.

inner wall 3 of the sides, is sweatcd or otherwise permanently made watertight. Also, to secure two distinct compartments, and to re: inforce the structure of the boat, the air tight joint is formed between the inner walls of the sides and the bottom Wall 10 of the bot tom, as particularly developed in Figure 4. In addition to this, the outer walls of the sides and the bottom wall of the bottomarc formed with inturned or rolled joints 11, as

shown in Figure 4, and such joints are sweated to secure watertightness and additional strength. These longitudinally extending seams are protected by means of a channel like member 12 riveted and sweated in place, so that no mechanical damage can occur with reference to these seams. a

Further, in order to facilitate the placing of the cork in the sidecompartments, the construction indicated in Figure 3 is followed. The outer wall of the sidesdoes not extend to the top of the inner wall 3. Instead, an auxiliary angular member 13 is employed and an outwardly projecting clinched seam 14 is formed between this memher and the outer Wall 4. Further, the member 13 is joined tothe wall 3 by means of the rolled and sweated seam 15. By having all of the seams sweated, the utmost strength is secured.

In addition'to this, the outwardly extending rib formed by the seam 14, increases the strength of the boat materially. Each side wall has a longitudinally extending spacer adjacent the upper edge positioned between the members 3 and 4 and embraced by the member 13.

In order to form an effective finish for the boat a quarter round strip 16 is secured at the flange or seam 14. In addition to this, immediately below the flange 14, a bumper strip 17, preferably of wood, is positioned and receives the shocks or blows normally imparted to a boat, as for example, when it bumps against a pier or landing.

It is to be noted that the compartments arc filled with a very buoyant material, such as cork, for example. This cork may be used in slab form, or may be ground. Further, by means of the transverse beams 6, the boat is thoroughly braced between the walls, in addition to the rigidity furnished by the metal construction. A suitable keel 18 is provided at the center bottom portion of the boat. It will be seen that the cork filling does not materially increase the weight of the boat,

cation of the several buoyant or air tight compartments. It is to be noted further, that by having these'compartments distinct I andseparate, injury toone does not affect the other. Further than this, having them packed withcork"prevents their flooding,

even if they. become open by an actual cut through the outer wall of the boat. Further, the'construction is such that the water will be prevented from freely traveling even comd pletely through one compartment in case of an actual tear or cut through the outer wall. From actual practice of this invention; it has been found thatthe boat has remarkable rigidity, andhas the other characteristics so much desired in boats of this type.-

It is also remarkably light Weight and may be easily driven by an ordinary detachable propulsion motor. r

Although the invention has been described in considerable detail, such description is intended as illustrative rather than limiting as theinvention may be variously embodied and as the scope of such invention is to be determined as claimed.

' I ela'iini I. Anons-inkable boat, comprising a body portion having a'botom and side walls formed of spaced metal members, each side wall having-alongitudinally extending spacer adjacent its'upper edge positioned between said metal members and the outer member having a separate member of angular cross section joined thereto by an outwardly projecting seam and joined to the inner wall at the top edge of the boat.

7 2. A non-sinkable boat, comprising a body portion having a bottom and side walls formed of spaced metal members, each side wall having a longitudinally extending spacer adjacent their upper edges positioned between said metal members and the outer member having a separate member of angular cross section joined thereto by an outwardly projecting seam and joined to the inner wall at the top edge of the boat, a bumper strip positioned below said outwardly extending seam, and a finishing strip positioned above said outwardly extending scam, whereby said outwardly extending seam is protected, and a bumper strip is furnished for receiving blows normally transmitted to the body of the boat.

3. A non-sinkable boat having a body portion having side walls formed of spaced metal members, the outer metal members of the sides and bottom meeting in longitudinally extending seams, angular plates spanning and protecting said seams and forming additional bracing members and contacting with the body portion on opposite sides of said seams, and fasteners located at one side and free of said seams and securing said angular plates to said body portion.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of Viscousin.
